How to Play Binairo

Binairo is a logic puzzle played on a rectangular grid. Your goal is to fill the entire grid with 0s and 1s while following three simple rules:

No more than two consecutive 0s or 1s: You cannot have three or more identical numbers in a row or column. For example, "000" or "111" is not allowed.
Equal number of 0s and 1s: Each row and each column must contain an equal number of 0s and 1s. In a 6×6 grid, each row and column must have exactly three 0s and three 1s.
Unique rows and columns: No two rows can be identical, and no two columns can be identical. Each row and column must have a unique pattern.

These simple rules create surprisingly complex puzzles that require careful planning and logical deduction. Unlike games based on luck, every Binairo puzzle can be solved through pure logic!

Tips and Strategies

Start with pairs: Look for positions where two identical numbers are already placed. The cell between them must be the opposite number.
Count remaining numbers: Keep track of how many 0s and 1s are left to place in each row and column.
Check for forced moves: When a row or column has reached its limit of 0s or 1s, all remaining empty cells must be the other number.
Look for unique patterns: If a row is almost complete and matches another row, the remaining cells must differ.
Use the hints wisely: Don't be afraid to use hints when learning. They explain the logic behind each move.
